This is a discussion on Does anyone have a used/new poker beer cap set. within the online poker forums, in the General Poker section; I found this poker set on facebook, and was wondering if anyone has seen it in person or used one?
I can't find much regarding reviews,

I don't think this set is from the website you posted, but I searched "beer poker chips" on Ebay and found this listing: http://www.ebay.com/itm/Beer-Cap-Poker-Chip-Set-/252392930667?hash=item3ac3ca7d6b:g:oxwAAOSw3mpXD~50. I've also seen similar sets on Etsy.com before... maybe check there as well
